Aerospace Work Platforms - More than Meets the Eye

Aerospace & Defense Technology: June 2019

  • Magazine Article
  • 19AERP06_13
Published 2019-06-01 by SAE International in United States

Today's work platforms are far more complex than the simple designs of the past.

For maintenance personnel in the aerospace industry to do their jobs effectively, they need to be able to get physically close to the equipment they are working on. This statement sounds obvious, but in order to meet this requirement, it is very important to utilize quality work platforms. Although most people are familiar with the basic uses of work platforms, there is not always much thought given to everything that goes into their design and fabrication.

Graphene-Silicon Devices for Optoelectronics Applications

  • Magazine Article
  • TBMG-34628
Published 2019-06-01 by Tech Briefs Media Group in United States

Silicon is a naturally occurring material commonly used as a semiconductor in electronic devices; however, researchers have exhausted the potential of devices with semiconductors made of silicon only. These devices are limited by silicon’s carrier mobility — the speed at which a charge moves through the material — and indirect bandgap, which limits its ability to release and absorb light.

Cooperative Ramp Merging System: Agent-Based Modeling and Simulation Using Game Engine

SAE International Journal of Connected and Automated Vehicles

Agent-based modeling and simulation (ABMS) has been a popular approach for modeling autonomous and interacting agents in a multi-agent system. Specifically, ABMS can be applied to connected and automated vehicles (CAVs) since CAVs can operate autonomously with the help of onboard sensors, and cooperate with each other through vehicle-to-everything (V2X) communications. In order to improve energy efficiency and mobility of traffic, we have developed an online feedforward/feedback longitudinal controller for CAVs to cooperatively merge at ramps. Agent-based CAV models were built in the Unity3D environment, where vehicles are given connectivity and autonomy through C#-based scripting application programming interface (API). Agent-based infrastructure model is also built as a Unity3D simulation network based on the city of Mountain View, California. A simulation of cooperative on-ramp merging is carried out with a distributed consensus-based protocol, and then compared with the human-in-the-loop simulation where the on-ramp merging vehicle is driven by four different human drivers on a driving simulator. The benefits of introducing the proposed protocol are evaluated in terms of travel time, energy consumption, and pollutant emissions. The…

May Mobility is building a unique business model around AV shuttle services, explains COO and co-founder Alisyn Malek.

Entering the busy headquarters of May Mobility, my eyes fix almost immediately on a huge red Corvette brake caliper sitting on a tool cart beside an engineer's work station. “You guys must be planning some really fast self-driving shuttles,” I quip to COO and co-founder Alisyn Malek moments later, when she greets me for our interview.

Designs to Dye for: Autonomy's New-Materials Revolution

Autonomous Vehicle Engineering: May 2019

From pineapples to bacteria, Envisage's research is focused on new mobility's ‘inside’ story.

Evolving vehicle engineering constantly reshapes vehicle architectures. But along with electrified drive-trains and autonomous capabilities is the need for a mindset shift in materials, opening the way for new sustainable solutions in color, materials and finish (CMF). Future cabins could have pineapple, banana, coconut and eucalyptus among the material solutions-with bacteria playing a potentially positive role.

A step-change in the cost of CFRP

Williams Advanced Engineering reveals secrets behind its innovations aim to move carbon fiber into the mobility mainstream.

A joke in the auto industry about CFRP (carbon fiber reinforced polymer) is that the “C” stands for “costly.” So, any manufacturing process that solves this significant drawback of the ultra-lightweight material's use outside of Formula One racing and exotic supercars, could change the vehicle-production game.

Feasibility Analysis of Taxi Fleet Electrification using 4.9 Million Miles of Real-World Driving Data

National Renewable Energy Laboratory-Matthew Moniot, Clement Rames, Erin Burrell
Published 2019-04-02 by SAE International in United States
Ride hailing activity is rapidly increasing, largely due to the growth of transportation network companies such as Uber and Lyft. However, traditional taxi companies continue to represent an important mobility option for travelers. Columbus Yellow Cab, a taxi company in Columbus, Ohio, offers traditional line-of-sight hailing as well as digital hailing through a mobile app. Data from Columbus Yellow Cab was provided to the National Renewable Energy Laboratory to analyze the potential for taxi electrification. Columbus Yellow Cab data contained information describing both global positioning system trajectories and taxi meter information. The data spanned a period of 13 months, containing approximately 70 million global system positioning system points, 840 thousand trips, and 170 unique vehicles. A variety of scenarios were evaluated using Columbus Yellow Cab data and the Electric Vehicle Infrastructure Projection Tool (EVI-Pro) to understand challenges and opportunities associated with operating an electrified taxi fleet. Two main factors-access to home charging and vehicle specifications-are shown to be major variables affecting successful electric fleet operation. The analysis indicates that 95.7% of taxi travel days can…

Analyzing and Preventing Data Privacy Leakage in Connected Vehicle Services

Ford Motor Co., Ltd.-Yu Seung Kim, Pramita Mitra
University of Michigan-Huaxin Li, Di Ma, Brahim Medjahed
Published 2019-04-02 by SAE International in United States
The rapid development of connected and automated vehicle technologies together with cloud-based mobility services are revolutionizing the transportation industry. As a result, huge amounts of data are being generated, collected, and utilized, hence providing tremendous business opportunities. However, this big data poses serious challenges mainly in terms of data privacy. The risks of privacy leakage are amplified by the information sharing nature of emerging mobility services and the recent advances in data analytics. In this paper, we provide an overview of the connected vehicle landscape and point out potential privacy threats. We demonstrate two of the risks, namely additional individual information inference and user de-anonymization, through concrete attack designs. We also propose corresponding countermeasures to defend against such privacy attacks. We evaluate the feasibility of such attacks and our defense strategies using real world vehicular data.
